Abstract

The utility model discloses a ceiling lamp which comprises a box body and a box cover arranged on the box body, wherein a lamp tube is arranged in the box body and a reflective sheet is arranged at the bottom of the box body. The ceiling lamp is characterized in that a reflective cover is fixedly arranged on the box cover. After light rays reflected from the reflective sheet are reflected again by the reflective cover on the box cover, the light rays radiated from a main lighting zone are strong and are uniformly distributed and the light rays radiated from an auxiliary lighting zone is weak. Thus, the light rays radiated from the main lighting zone and the auxiliary lighting zone have obvious strength comparison so that the lighting effect is good. Meanwhile, because the reflective cover is stuck on the box cover, the reflective cover can also be turned over together when the box cover is opened. Thus, the utility model has large space to conveniently install and change parts in the box body, such as the lamp tube, etc.

Description

A kind of lamp affixed to the ceiling

[technical field]

The utility model relates to a kind of lamp affixed to the ceiling.

[background technology]

Lamp affixed to the ceiling in the market is provided with the reflector plate that strengthens the light reflection in the bottom of its casing, but the light that reflects is not because to penetrating all around, light is concentrated, thereby has influenced illuminating effect, has weakened the illuminating effect of lamp affixed to the ceiling greatly.

[summary of the invention]

The purpose of this utility model is to overcome the deficiencies in the prior art, a kind of good illumination effect is provided, has changed the easy lamp affixed to the ceiling of parts.

In order to solve the technical problem of above-mentioned existence, the utility model adopts following technical proposals:

A kind of lamp affixed to the ceiling includes casing and the case lid that is contained on the casing, and the bottom that fluorescent tube and casing are installed in casing is provided with reflector plate, it is characterized in that being installed with on case lid reflector.

Aforesaid a kind of lamp affixed to the ceiling is characterized in that reflector is tapered, is set to numerous prismatic reflex block at the reflector inwall.

Aforesaid a kind of lamp affixed to the ceiling is characterized in that case lid includes transparent glass, and glass is divided into key lighting district and secondary surround, and wherein just the big end of taper with reflector is corresponding in the zone in key lighting district.

Aforesaid a kind of lamp affixed to the ceiling is characterized in that being coated with densely covered dot on the secondary irradiated region of case lid.

Aforesaid a kind of lamp affixed to the ceiling, the diameter that it is characterized in that dot is 0.5～2mm, is spaced apart 0.8～4mm between the adjacent round dot.

Aforesaid a kind of lamp affixed to the ceiling is characterized in that being coated with grid lines on the secondary irradiated region of case lid.

Aforesaid a kind of lamp affixed to the ceiling is characterized in that the grid lines live width is 0.5～1.5mm, is spaced apart 0.8～3mm between the adjacent net ruling.

Compared with prior art, the utlity model has following advantage: 1) light that is penetrated by the key lighting district through the reflector on the case lid reflects again after from the light of reflector plate reflection by force and be evenly distributed, and the secondary light that penetrates according to the district a little less than, like this from the key lighting district, the light power that penetrates of secondary surround is relatively distincter, thereby can make illuminating effect better; 2) because reflector is to stick on the case lid, reflector is also and then routed up together when opening case lid, so just has bigger space to install, change the interior parts such as fluorescent tube of casing more easily.

Fig. 2 is a upward view of the present utility model;

The front view of glass when Fig. 3 is another embodiment.

[specific embodiment]

Below in conjunction with the accompanying drawing and the specific embodiment the utility model is described in further detail:

A kind of lamp affixed to the ceiling includes casing 1, and case lid 2 has been installed on casing 1, is provided with fluorescent tube 3 in casing 1, and during energising, the effect of playing illumination is gone out in the light that fluorescent tube 3 sends transmission from case lid 2.

Case lid 2 includes the collar 4 and transparent glass 5, and glass 5 is fixedly mounted on the collar 4, and case lid 2 is contained on the casing 1, is provided with rotating shaft 6 between case lid 2 and casing 1, and case lid 26 rotations is around the shaft opened.Be provided with spring leaf 7 at case lid 2 away from a side of rotating shaft 6, when case lid 2 is closed casing 1, be stuck on the casing 1, make case lid 2 can not drop out casing 1 by spring leaf 7; When will opening case lid 2, when for example needing to change fluorescent tube 3, pin spring leaf 7 and pull down, just can pull out case lid 2 one sides and case lid 26 can be opened after rotating around the shaft.Glass 5 is divided into key lighting district 8 that penetrates for main light and the secondary surround of penetrating for all the other light 9.

In order to improve the effect of illumination, be provided with on reflector plate 10 and the case lid 2 in the bottom of casing 1 reflector 11 is housed.The one side that reflector plate 10 relies on fluorescent tube 3 is a smooth flat, reflects away from glass 5 to strengthen light.Reflector 11 is a cone-shaped, and slightly little at the end near casing 1 bottom, slightly larger at an end that is affixed to glass 5, it equates with the region area in key lighting district 8.Reflector 11 is used to strengthen the aesthetic feeling of the reflecting effect and the whole lamp of light, is set to the reflex block 12 of numerous prismatic at the inwall of reflector 11, so that reflection ray.Reflector 11 is sticked on the glass 5 of case lid 2 with glass cement transparent, heatproof, at this moment just the big end with reflector 11 tapers is corresponding in the zone in the key lighting district 8 of glass 5, the light that reflects from reflector plate 10 is penetrated on the prismatic reflex block 12 of reflector 11 inwalls like this, and distribution of light is evenly penetrated by the key lighting district on the glass 58 back.The secondary surround 9 of glass 5 is the zone beyond the key lighting district 8, the dot 13 that spraying is evenly distributed on secondary surround 9, and the diameter of dot 13 is 0.5～2mm, is spaced apart 0.8～4mm between the adjacent round dot, as shown in Figure 2.

Also can spray the grid lines 14 that is evenly distributed on the secondary surround 9 of case lid 2, the live width of grid lines 14 is 0.5～1.5mm, is spaced apart 0.8～3mm between the grid lines 14, as shown in Figure 3.

Light is during through secondary surround 9, can only go out from the regional reflex beyond dot 13 or the grid lines 14, so dot 13 or grid lines 14 can be used to weaken the light intensity of launching from secondary surround 9, like this from key lighting district 8, the light power that penetrates of secondary surround 9 is relatively distincter, thereby further illuminating effect.

During parts in installing or change casing 1 such as fluorescent tube 3, pin spring leaf 7 and pull down, open case lid 2 after, reflector 11 on the case lid 2 is also and then taken casing 1 out of, so the space in the casing 1 is enough big, changes parts for the user, dismounting is got up very convenient like this.
