Abstract
The utility model discloses an LED (light emitting diode) desk lamp, which comprises a lamp head, a lamp holder, a connecting rod and a constant current direct current power supply, wherein the lamp head comprises a casing, a light transmission cover, an LED lamp board and a heat radiation board, the LED lamp board and the heat radiation board are arranged in a volume cavity arranged between the casing and the light transmission cover, a plurality of heat radiation through grooves are formed in parts, corresponding to the heat radiation board, on the casing, the connecting rod comprises a metal hose and a plastic cement hose sheathed outside the metal hose, the lamp head end of the metal hose is in contact connection with the heat radiation board through a metal connecting element, the constant current direct current power supply is arranged in the lamp holder, the LED lamp board and the constant current direct current power supply are electrically connected through a conducting wire arranged in the metal hose in a penetrating way. The heat radiation board is in contact connection with the metal hose of the connecting rod through the metal connecting element, the heat on the heat radiation board can be favorably conducted to the connecting rod, so the heat radiation of an LED can be accelerated, the rotation at any angle can be realized through the flexible metal hose, complicated support frame and rotating shaft structures are omitted, and the use and the storage are more convenient.
Description
Technical field
The utility model relates to a kind of LED desk lamp, refer to especially a kind of simple in structure, dispel the heat LED desk lamp good.
Background technology
LED desk lamp is the desk lamp take LED as light source, as the third generation lighting engineering after incandescent lamp, fluorescent lamp, has energy-saving and environmental protection, safe and reliable feature, and market prospects are wide.There are the following problems in design process for LED desk lamp: the one, and the heat dissipation problem of LED light source, as dispel the heat the bad service life that can affect LED; The 2nd, traditional desk lamp regulates in order to realize multi-angle, thereby support and rotating shaft are designed too complicatedly, not only increase cost, and structural stability also can reduce.
Utility model content
The purpose of this utility model be to provide a kind of simple in structure, dispel the heat LED desk lamp good.
For achieving the above object, the technical solution adopted in the utility model is as follows:
A kind of LED desk lamp, comprise lamp holder, lamp socket, connecting rod and constant current dc source, described lamp holder comprises housing, diffuser, LED lamp plate and heat sink, LED lamp plate and heat sink are placed in the cavity volume between housing and diffuser, and on housing, the part of corresponding heat sink is provided with the groove of some heat radiations; Described connecting rod comprises metal hose and is placed on the plastic hose outside metal hose; Lamp holder one end of this metal hose is connected with described heat sink contact by the connector of metal; Described constant current dc source is loaded in lamp socket, between LED lamp plate and constant current dc source, is electrically connected by the wire being arranged in metal hose.
The beneficial effects of the utility model are: heat sink contacted and are connected by metal connecting piece with the metal hose of connecting rod, be conducive to the heat on heat sink to conduct to connecting rod, thus the heat radiation of quickening LED; Flexible metal hose can be realized rotation at any angle, has saved complicated support and pivot structure, uses and stores all more for convenience; Desk lamp appearance entirety is plastic cement material parcel, good insulation preformance, and be difficult for breaking.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is described further:
Fig. 1 is the cross-sectional view of LED desk lamp in embodiment.
The specific embodiment
With reference to figure 1, a kind of LED desk lamp, comprise lamp holder 1, lamp socket 2, connecting rod 3 and constant current dc source 4, described lamp holder 1 comprises housing 11, diffuser 12, LED lamp plate 13 and heat sink 14, LED lamp plate 13 and heat sink 14 are placed in the cavity volume between housing 11 and diffuser 12, and on housing 11, the part of corresponding heat sink 14 is provided with the groove 111 of some heat radiations; Described connecting rod 3 comprises metal hose 31 and is placed on the plastic hose 32 outside metal hose 31; Lamp holder one end of this metal hose 31 is connected with described heat sink 14 contacts by the connector 5 of metal; Described constant current dc source 4 is loaded in lamp socket 2, between LED lamp plate 13 and constant current dc source 4, is electrically connected by the wire being arranged in metal hose 31.Heat sink 14 is contacted and is connected by metal connecting piece 5 with the metal hose 31 of connecting rod 3, be conducive to the heat on heat sink 14 to conduct to connecting rod 3, thus the heat radiation of quickening LED; Flexible metal hose 31 can be realized rotation at any angle, has saved complicated support and pivot structure, uses and stores all more for convenience; Desk lamp appearance entirety is plastic cement material parcel, good insulation preformance, and be difficult for breaking.
Above embodiment is just explanation rather than restriction the utility model, and the equivalence of doing according to the method described in the utility model patent claim therefore all changes or modifies, and is included in the utility model patent claim.
