Description

A kind of energy-saving lamp

Technical field

The utility model relates to a kind of illuminating energy-saving lamp.

Background technology

In modern industry domestic lighting electrical equipment, people adopt in a large number and a kind ofly can directly connect the electricity-saving lamp that power supply is used for throwing light on, and it mainly is applicable among the lamp ornaments lighting functional area of various standards in the world, its model includes: E14, E27, B15d, B22d, G23, GU10... etc.Since progressively replacing tradition crow silk lamp from electricity-saving lamp, the use of electricity-saving lamp is more and more general, electricity-saving lamp is incandescent bright, can save power supply, but the electricity-saving lamp of existing various existing models is the sealed electricity-saving lamp of fluorescent tube of GU10 producing a kind of model all as at present a lot of producers, also exist energy of light source not obtain cmpletely utilization, the design of the radiator structure of light fixture is unreasonable, the significant degree deficiency of can't dispelling the heat or dispel the heat, influence electricity-saving lamp luminous with problem such as service life.

Summary of the invention

The purpose of this utility model is to propose a kind of utilization rate that can improve energy of light source, and can effectively solve the fluorescent tube heat radiation, improves the improved energy-saving lamp that light fixture uses.

The energy-saving lamp that the utility model is designed, comprise plastic housing, electronic circuit board combination and power saving fluorescent lamps combination, described plastic housing has three sections of upper outlet body, middle cover body and lower covers, its upper outlet body is more small-bore cylindrical shape, lower cover is the cylindrical shape of larger caliber, cover body is a truncated cone-shaped cover tube in described, and it and upper outlet body and lower cover kissing connect; The internal perisporium of described lower cover is set with a reflection shield tube, the sidewall of cover body has been arranged a plurality of louvres in described, the louvre of faceshield side wall communicates in described reflection shield tube top perimeter is also arranged a plurality of louvres and cloth is come, the power saving fluorescent lamps combination is fixed on the interior top of chamber of reflection shield tube, electronic circuit board combination is fixed on the reflection shield tube and places among the cover body of plastic housing, pad is separated with heat sink between electronic circuit board combination and reflection shield tube, and the louvre that the tube line of power saving fluorescent lamps combination passes on the reflection shield tube is connected in the electronic circuit board combination through the fairlead of heat sink again.

The louvre that cloth comes described middle faceshield side wall can adopt following design: louvre is by 3～5 groups, and every group 3～5 hole constitutes along the equally distributed hole of faceshield side wall group, as 32 louvres can be set, be divided into 4 groups, row is evenly divided along the faceshield side wall grouping in every group 4 hole; And that cloth comes the hole count of louvre of described reflection shield tube top perimeter is corresponding with the louvre of middle faceshield side wall with arrangement.Design can guarantee efficiently radiates heat like this, and elegant in appearance.

The louvre in described on the faceshield side wall and the louvre of reflection shield tube top perimeter can be perpendicular long waist shape, rectangle, also can be circle.

Described reflection shield tube generally adopts aluminum reflection shield tube.

Can also the decoration line be set at the lower limb of the lower cover of described plastic housing, as the decoration line of belt wheel profile of tooth, to strengthen the decorative effect of this energy-conservation light fixture.

The design of this energy-conservation light fixture, owing to structurally increased the reflex reflector parts of reflection shield tube, on these reflex reflector parts and on the plastic housing of energy-saving lamp reasonable heat dissipation holes is being set simultaneously, thereby the energy of light source that has improved this energy-conservation light fixture greatly makes full use of rate and the effective emission rate of heat, can prolong electricity-saving lamp actual life to a certain extent.This energy-conservation light fixture also has rational in infrastructure, and good looking appearance is generous, advantages such as economy and durability.

The specific embodiment

Be described in further detail below in conjunction with the CONSTRUCTED SPECIFICATION of accompanying drawing the utility model embodiment:

As shown in Figure 4, this energy-conservation light fixture is made of five metals

conduction electrode parts

1 and 1a, plastic housing 2, electronic circuit board combination 3, thermal insulation board 4, aluminum reflection shield tube 5, power saving fluorescent lamps combination 6 and light cover 7; Described plastic housing 2 has 23 3 sections of upper outlet body 21, middle cover body 22 and lower covers, five metals conduction electrode parts 1 are equipped with at the top of upper outlet body 21, the sidewall of middle cover body 22 is arranged the louvre 2a of 32 perpendicular long waist shapeds, these louvres, be divided into 4 groups, row is evenly divided along the faceshield side wall grouping in every group 4 hole, is provided with the decoration line 2b of belt wheel profile of tooth at the lower limb of lower cover 23; Corresponding with the louvre on the sidewall of middle cover body 22, aluminum reflection shield tube 5 top perimeter have been arranged 32 louvre 5a; Assembly such as Fig. 2 of this energy-conservation light fixture, shown in Figure 3, reflection shield tube 5 is sleeved on the internal perisporium of described lower cover 23, power saving fluorescent lamps combination 6 is fixed on the interior top of chamber of aluminum reflection shield tube 5, electronic circuit board combination 3 is fixed on the reflection shield tube 5 and places among the cover body 22 of plastic housing 2, pad is separated with heat sink 4 between electronic circuit board combination 3 and reflection shield tube 5, the louvre 5a that the tube line of power saving fluorescent lamps combination 6 passes on the reflection shield tube 5 is connected in the electronic circuit board combination 3 through the fairlead of heat sink 4 again, and two power supply input lead 3a in the electronic circuit board combination 3 are connected with 1a with five metals conduction electrode parts 1 respectively with 3b.Light cover 7 is fixed on the plastic housing 2 by viscosity heatproof glue.The energy-saving lamp finished product of making as shown in Figure 1.
